Levitation is defined as the rising of a body in air by supernatural means. Historically, there have been many levitating saints. In a way, we also "levitate" as we get to know the Lord. At the beginning, we are deeply immersed in the world and attached to the many things of the world. The result is that we feel heavily weighed down and tired. As we know God through Christ more and more, the burden gets lighter and lighter until finally, we are in union with him and feel like being lifted up into air in total freedom. So it is like levitation, but the rising just took a lot longer.
